IM PROVEM ENT IN BU RNERS l FO Specification forming part of Letters Patent No. 71,430, dated November 26,1 1867. p

To all `whom it may concern:

Be it known that I, AARON C. VAUGHAN, of

an Improved Burner for Locomotive Head Lights; and `I do hereby declare the following to` be a full, clear, and 'exact description of the same.

My invention consists of certain improveers for locomotive head-lights; vthe object of In order to enable others skilled inthe art specification," and in which- Figure l is a vertical'section of my improved lamp-burner for locomotive head- 4, parts of Fig. 1, drawn to an enlarged scale.

l A` isa perforated casing, on the under Vside` of: which `is a projection, a, and into the latthroughtheburner, and terminates at the top in a disk or buttomb, the rod being {secured after adjustment by a nut, a.

To the casing A is secureda tube, D, and

E,`hav1ing screw-threads on its exterior sur-` on ,this tube `F slides a ferrule, G, having tween the said tube IF andan exterior tube, I. Pins e project from the ferrule G, and

tweenithe threadsof the screw on the tube E. The tubes E and I are connected together at the bottomfso as to form an annular reservoir, for containing the oil or other burningfluid and the wick, the oil being admitted The` whole of the tubes D, E, F, and I ter- `the top ofthe tubeD areradial arms f, meeting at a central hub, through which passes the rod B, and by which the latter is guided.`

Over the tube I fits a detachable tube, k,

above the top of the above-mentioned tubes,`

the centrall opening of thisdoine being such i that its edge a; shall occupy thefposition, or Fig;` 3,inrespect about the position, shown in to the tubes and Wick.`

An inclined annular ing m, this shield being turnedup atthe lower edge, so as to form a recess for the reception of the lower end of the glass chimney,

In the shield M is; an` annular `rowof small" holes, t, through which the air canipassfrombe low in the direction `of the l arrow," betwee the flame and the glassfehimney, and preven the former from impin ging lagainst the latte While the shield M servesito` supportytthe chimney, it forms, with `the perforated casin lm, an annular chamber for directing the a to` and through the perforations, andatfth same time the flickering `of the lila-me by th agitation of the air outsidetheburner ispre` vented.

I have found that bythispeeuliar construe-1 j tion and arrangement of easingm, dome-like top n of the same, and shield Main respectto` the wick, a-most brilliant and steady lilame is l p produced.l At the same time boththe topof` 1 the burner and its stem are sc fconstructed as I not'to interfere with the reiieeting power of the head-light. i It is necessaryfrom time to time to `adjust the disk or button b, and occasionally to lower it so far that it will `extinguish the flame.

Heretofore it has been usual toadjust the I i disk from above-a somewhat dicult and tedious task,owing,toxit`s heat andthe necessityof removing thelchimney.l In `myyim` provement, however, theextension of the rod" B through the burner permits the ready ad` C justmentof the diskfrombelow, whereneither l the heat nor;` the chimneywill interferewith i i the operation.

I claim asmy lnvention and desire tOse-l 1 and cure by Letters Patente- `1. The perforatedcasing m, shield intervening space between the two. 2. The openingsti `1 the `sh`e1d purpose specified.

In testimony whereof I have signed my name` 3 to this specification in the presence of two l subscribing witnesses. i j AARON 0l. VAUGHAN.
